Bet he knows that already, after all he ported some cool emulators already, i?d say Chui looks for such stuff:
sudo hwinfo --framebuffer
Mode 0x0300: 640x400 (+640), 8 bits
Mode 0x0301: 640x480 (+640), 8 bits
Mode 0x0303: 800x600 (+800), 8 bits
Mode 0x0305: 1024x768 (+1024), 8 bits
Mode 0x0307: 1280x1024 (+1280), 8 bits
Mode 0x0340: 1400x1050 (+1400), 8 bits
found at a german Ubuntu site
after searching for pixelmodes.
Possibly unrelated, but thought i?d post. Oh and before you try, dingux does not contain hwinfo, just tried myself...
If this post is totally useless, forget it please.
